What mod chip is easiest to install and use...and are mod chips even worth it?

I read a lot of posts here and see that many are using different mod chips. Some are having problems...some are not.

I'm not interested in using a mod chip for anything other then to play copies of games that I have backed up. I see that many are having problems and wonder if adding a mod chip is even worth the trouble.

Any advice on what chip would be best for me is appreciated. I have xBox v1.1

By the way...I prefer a solderless mod chip. I don't want to be messing with soldering my kid's xBox and ruining the thing...however I will solder if the mod chips are better then solderless.

I got an xecuter2 solderless (pogo pins) only tricky bit is making a good connection on the d0 of the xbox motherboard, a tiny blob of solder on the board helped.
The cromwell flashbios is real easy to reflash, stick a cd in with the new bios on, and youre away.
asking if theyre worth it?
oh hell yea
